What follows is a quick overview of what I did to build a universal application from Stellarium 0.8.1 sources on an Intel Mac.

Contents

1) The source code for Stellarium 0.8.1. You can check them out of CVS (see the source forge pages for details) or simply download a source tarball from here. They are in the file stellarium-0.8.1.tar.gz Note that building from the tarball is easier than building from CVS.

2) A ready made Xcode project for building Stellarium on Mac OS X. You can download the file macosx-xcode.tar.gz containing such project from here. I choose revision 1.4.

3) An Intel or PPC Mac with a recent version of the developer tools installed. I used Xcode 2.4.

4) If you are building from CVS, you will need to install Fink and several packages; if you are building from a tarball, Fink is optional.

After extracting the archives you should have two folders, one named stellarium-0.8.1 and the other named macosx. Make sure to place the macosx folder into the stellarium-0.8.1 folder, as this is essential for successful project building.

Step by Step Instructions:

1) Open a terminal window. These instructions will assume that you know how to use Terminal and have some familiarity with UNIX commands.

At this point one would expect to build the project, but after some work the compiler complains and stops the build. Instead, you must first perform some of the steps done to build the Linux version of Stellarium. These steps will differ depending on whether or not you have Fink installed.

These steps actually seem more complicated than building without Fink, but they are actually needed if you build from a CVS checkout instead of a tar ball.

0) Make sure you have the SDL and SDL-mixer packages installed. We will actually be using the version of SDL-mixer that is included with the macosx-xcode.tar.gz file, but we need other SDL-mixer files to get configure to run correctly.

1) You need to run configure just as if you were doing a Linux build. To get configure to work, you must set some environment variables and create a symbolic link. In the stellarium directory, in the terminal application, paste the following commands:

If you want to build an universal binary you have to modify the build settings of the Stellarium target, since they are for a PPC architecture.
Open the Stellarium target properties, choose the build tab and add the i386 architecture to the Architectures setting (double click on the row and check the i386 checkbox).

This must be done for all configurations for which you want to build a universal binary.

After following the previous steps you should be able to build the project and run Stellarium natively on a Intel Mac.
On my machine (Core 2 Duo 2.16 Mhz and NVIDIA 7600 GT) the fps averages 35-45 versus 8-9 frames of the PowerPC interpreted version.

If you have have an ATI graphic card it is perfectly possible that Stellarium doesn't work anyway. I read somewhere (don't remember exactly) that there is an OpenGL bug in the ATI driver, and it could be the reason why Stellarium doesn't work on MacBook Pro or other Intel Macs with ATI cards.

In that case you must be patient and wait for MacOS 10.4.8, where it will be likely fixed.
